Where to Find the Serial Number on a Firearm
Quick answer: The serial number is engraved or stamped on the frame or receiver of the firearm — the location varies by manufacturer and type.
Under federal law (Gun Control Act of 1968), all licensed firearm manufacturers must engrave a unique serial number on every firearm produced. Here's where to find it by type:
Handguns (Pistols)
Frame, near trigger guard or grip. Also may be on the slide or barrel.
Revolvers
Frame above the trigger, on the butt of the grip, or on the crane.
Semi-Auto Rifles (AR-15, AK-pattern)
Lower receiver, typically near the magazine well or pistol grip.
Bolt-Action & Lever-Action Rifles
Receiver (the metal housing), often bottom or side.
Shotguns
Receiver, near the trigger group.
Revolvers (Smith & Wesson)
Butt of the grip, cylinder crane, and frame.
If the serial number has been removed, altered, or defaced, do not purchase the firearm. Under 18 U.S.C. § 922(k), it is a federal felony to possess a firearm with an obliterated serial number — even if you did not remove it yourself.
Which Databases Does SafeOrStolen Check for Firearms?
Quick answer: SafeOrStolen queries FBI NCIC (via authorized data partners), ATF eTrace records, HotGunz, and all 50 state law enforcement stolen property systems simultaneously.
No single database captures all stolen firearms in the United States. Theft reports may be filed at the local, county, state, or federal level — and different agencies maintain different records. SafeOrStolen runs parallel queries across all available sources so you get the most complete picture possible.
FBI NCIC (National Crime Information Center)
The primary federal stolen gun database, queried by law enforcement nationwide. SafeOrStolen accesses this data through authorized commercial aggregation partners. Note: Direct NCIC access is restricted to law enforcement — our results reflect commercially available NCIC-derived data.
ATF eTrace Records
ATF's firearm tracing system tracks the sale and transfer history of firearms used in crimes. eTrace-derived public data helps identify firearms that have been recovered at crime scenes.
HotGunz
The largest community-maintained stolen firearm database, with reports submitted directly by victims whose firearms were stolen. Complements law enforcement databases with private theft reports that may not have been formally filed with police.
All 50 State Law Enforcement Databases
Each state maintains its own stolen property registry. Our system queries all 50 simultaneously — critical because many theft reports are filed at the state or county level without making it into federal systems.
Insurance Theft Reports
Insurance company theft claim data provides an additional signal for firearms reported stolen through homeowner or renter's insurance but not necessarily through law enforcement.
Important disclosure: SafeOrStolen is a commercial aggregation service, not a law enforcement agency. We are not affiliated with the FBI, ATF, or any government agency. A clean result means no records were found in our aggregated database — it does not constitute a government clearance or guarantee the firearm has never been stolen.
Legal Risks of Buying a Stolen Firearm
Quick answer: Possession of a stolen firearm is a federal felony even if you unknowingly purchased it. Law enforcement can seize the firearm with no compensation to you.
This is not a minor civil matter. Buying a stolen gun — even unknowingly — creates serious legal exposure under both federal and state law:
- ⚠️
Federal criminal exposure
Under 18 U.S.C. § 922(j), knowingly purchasing, possessing, or transferring a stolen firearm is a federal felony carrying up to 10 years in prison. "Knowingly" is broadly interpreted — if you had reason to know the gun was stolen (low price, seller unwilling to provide paperwork), that can be sufficient.
- ⚠️
State criminal exposure
All 50 states have additional receiving stolen property statutes. Penalties vary but typically include felony charges for firearms.
- ⚠️
Asset seizure with no compensation
Law enforcement can seize a firearm linked to theft records at any time. You have no legal claim to compensation — your money is gone.
- ⚠️
Background check complications
A stolen firearm discovered during a transfer at a licensed dealer (FFL) will result in the transfer being denied and possible investigation of all parties involved.
Protect yourself before any private firearm transaction.
Check This Firearm Now — Free →Who Should Always Run a Gun Serial Check
Quick answer: Anyone buying, accepting, or reselling a used firearm — including private buyers, pawn shops, gun show attendees, estate sale participants, and FFL dealers.
🎯 Private Buyers
Anyone purchasing a used firearm through a private sale on Armslist, Facebook, at a gun show, or from an individual. Private sales in most states have no background check — the serial check is your only protection.
🎯 Pawn Shop Operators
Most states legally require pawn shops to run stolen property checks before accepting firearms as collateral or for sale. Our Business Plan generates the compliance-ready PDF certificate you need.
🎯 Gun Show Vendors & Attendees
High volume + cash transactions = elevated risk. Many stolen guns circulate through gun shows precisely because of lighter scrutiny. Run a check on every private transaction.
🎯 FFL Dealers Buying Used Inventory
When buying used firearms from individuals for resale, a serial check provides documented due diligence before you take ownership.
🎯 Estate Sale Participants
Firearms in estates can have complex ownership histories. Verify before purchasing — you have no way to know the history of an inherited firearm.
🎯 Sellers Proving Legitimacy
Sellers can run a check on their own firearm and share the clean result with buyers — increasing buyer confidence and selling price.
Red Flags When Buying a Used Firearm
Quick answer: Never buy if the serial number is missing, altered, or if the seller refuses to allow you to write it down for verification purposes.
- 🚩Serial number is scratched, filed, or otherwise altered — federal felony to possess
- 🚩Seller refuses to provide the serial number or allow you to record it
- 🚩Price is significantly below market value for the model and condition
- 🚩Seller cannot produce original purchase receipt or documentation of transfer
- 🚩Seller is unusually eager to complete the sale quickly, especially in cash
- 🚩Firearm has aftermarket modifications that obscure the original serial number location
- 🚩Seller says they "found it" or received it as payment for a debt
- 🚩No box, accessories, or documentation that would normally accompany a legitimate sale

Pawn Shop Firearm Compliance Requirements
Quick answer: Most U.S. states legally require pawn shops to verify firearms against stolen property databases before accepting them. Failure to comply can result in criminal charges and loss of license.
Pawn shop operators face significant legal exposure when accepting stolen firearms. Unlike private buyers who may unknowingly purchase stolen property, pawn shops are considered sophisticated commercial buyers — courts hold them to a higher standard of due diligence.
